AN EXPERIMENTATION AND EFFECT EVALUATION ON SIMULATING A SMALL SCALE TRANSFORMER POOL FIRE

摘要

A small scale experiment involving 0.26 m diameter pool fires, with a 0.1 m diameter simulated transformer and with 1.5 cm diameter gravel stones around the transformer have been conducted. The gravel stones around the mock transformer reduce the flame height by 19% and the heat release rate by 32% compared to the data without gravel present. Fires were extinguished when the liquid level decreased to the gravel level. Also, the experiment proved once the transformer oil ignited the oil boiling, high heat release and sooty smoke accompany generation. The phenomena indicated that the manual fire fighting is very difficult during large transformer pool fire occurred.
